    Honestly replacing a 1/4 hp Trane fan for a 1/3 hp could be the correct motor with out really looking at the numbers. Factory (OEM) motors always seem to have more power to them than a generic one. Really have to match the amps of both motors. Since he went with a new motor; why he didn't replace the capacitors with generic ones is beyond me. New generic capacitors are rather cheap part, and should be replaced with the motor.

    Given that all ran fine for 2 years, do you think I'd be good if I replaced the generic motor with the same identical one BUT now replaced the run capacitor with the correct one made for this generic motor?

    i have swapped out many Trane condenser fan motors , some O.E.M. some NOT.

    they were always matched to the rpm , voltages, capacitor and the fan blade placed in the shroud like it should be ....................

    swapping a motor is a basic easy thing for a established and experienced tech to do. if the technician isn't sure what capacitor he should have used then he shouldn't be doing repairs... and if the company thinks this behavior is ok, you should be looking for a more qualified company.

    Making sure the cap matches the motor certainly sounds like a good idea. Making sure the motor matches the application sounds even better. I would not recommend this kind of thing as a DIY project. High voltages of electricity involved that could harm or kill. Also, a DIY person doing this may very well make some mistakes that could cause equipment damage and end up costing you more money than if you had a pro do it. I've seen it firsthand.

    I don't beleive that consumers have access to those resources. That information will come to you through a service company.

    do you have some numbers to match that info.? a link or study would be fine...

    my thinking is a 1/4 hp motor is a 1/4 hp motor regardless of brand or size...........

    unless you have a study of facts and a certified evaluation of the tests ..........

    otherwise im baffled that you would assume an emmerson 1/4 hp motor is
    more /less powerful than a 1/4 hp motor of another brand !

    It's a complicated subject. This article explains it a bit. After reading it, you can see why people say matching the amps is more important than what what a manufacturer says their motors HP is.

    Sorry for obviously ticking off at least one of you. Certainly wasnt my intent. Since I am brand new here and out of work for almost 2 years, I was merely looking for some assistance. Thanks to those of you who helped. For those you that are offended, (the one of you that I see) your demeanor speaks for itself. You must be the repairman of choice with such an attitude.
